To all whom it may concern Be it known that I, JosnrH SoNGNE, a citizen of the United States, residing at Jeanerette, in the parish of Iberia and State of ouisiana, have invented a new and useful Log-Dog Puller, of which the following is a specification.

The present invention appertains to a puller or extractor for chain dogs which are commonly employed in saw mills and the like, for handling logs, it being the object of the present invention to provide a lever or crowbar embodying novel and improved means for facilitating the withdrawal or extraction of such dogs from the logs into which they have been driven.

of the hook 9 to the lower end of the lever, above the tread or face of the cam 5. The hook 9 is provided at its free end with the bill 12 which is turned away from the cam 5. The abutment 8 is arranged to be engaged by the shank of the hook, whereby the hook will be supported at an angular position above the tip or end of the cam, the free end of the hook being spaced considerably from the tip of the cam as seen in Fig. 1.

In practice, the present device is employed for extracting log dogs, such as illustrated at 13, a pair of the dogs generally being connected by means of a short chain 14, the terminal links 15 of which are relatively large and are engaged to the butt ends of the With the foregoing and other objects in dogs. The dogs 13 are preferably in the view which will appear as the description form of bars or fiat pins, which are driven proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

he invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure l is a side elevation of the improved dog puller, as in use, a portion of the into the log to attach the chain 14. to the log for convenience in handling the log, as will be apparent to those versed in the art. Considerable difficulty is occasioned in withdrawing the dogs, according to prevailing practice, but the withdrawal of the dogs is rendered less difficult, by the employment of the improved device herein disclosed, as will presently appear.

In the use of the present implement, the bill 12 of the hook 9 is first engaged through the link 15 of the dog to be extracted, and the fork or claw 6 is then brought over the lever or crowbar being broken away. Fig. adjoining edge of the dog, with the cam 5 2 is a plan view of the device, a portion of caring against the log. The shank of the the lever being broken away, and the book being thrown back. Fig. 3 is a perspective view of a pair of log dogs, a portion of the chain connecting them being broken away.

In carrying out the present invention, there is employed an ordinary or prevailing type of lever or crowbar 4., the lower end of which is provided with a curved shoe or cam 5. The tip of the cam 5 is bifurcated to provide the fork or claw 6, and the lever 4 is provided directly above the fork or claw 6 with a narrow and deep recess 7, an abutment 8 being formed between the recess 7 and the bifurcation or fork 6.

In connection with the lever, there is employed a flat hook 9 which has an eye 10 at its butt end fitting snugly between the sides of the recess 7 a pin or rivet 11 being passed through the side walls of the recess 7 to engage through the eye 10 to pivot the shank hook 9 is designed to contact with or rest against the abutment 8, in order that when the lever is depressed, the hook will be swung upwardly, so as to withdraw the dog in a convenient manner. In some instances, the extraction of the dog may be facilitated by engaging the fork or claw 6 under the link 15, although this is not ordinarily necessary.

The lever or crowbar in the ordinary manner ment of the hook 9, by swinging the hook back as indicated in Fig. 2.

Having thus described the invention what is claimed as new is An. extracting implement embodying a lever having a cam at its lower end, and a recess above the tip of the cam, the tip of the cam being bifurcated, there being an abutment between the said recess and the bifur- 4 may be employed without the employcation, and a hook having its butt end pivmy own, I have hereto afiixed my signature oted Within the said recess, the shank of the in the presence of two Witnesses.

hook bein arran ed to contactwith the abutment to sfipport the hook at an angular po- O P SONGNE' sit'lon above the tip of the cam, and the bill WVitne'sses:
